/**

* @file Configure git to use .git-hooks/ as the local hooks dir. Replaces husky

* — same end-state (committed hook source + auto-install on `pnpm install`),

* one fewer dependency. Idempotent: re-running is a no-op when core.hooksPath

* already points at .git-hooks. Safe to invoke from `prepare`. Skipped when:

*

* - Not inside a git repo (e.g. running in a tarball install).

* - .git-hooks/ doesn't exist (e.g. the template scaffold hasn't been cascaded

* into this repo yet).
